Browser-Based 3D Scenes Now Run Billions of Points

Summary

Imagine viewing incredibly detailed three-dimensional scenes with over one billion points directly in your browser, a feat previously impossible without high-end hardware or downloads. This breakthrough is powered by an open-source library that makes these massive scans accessible on laptops and phones. The technology, called 3DGS splats, represents shape and color with tiny dots, offering more realistic visuals than traditional 3D. While previously hindered by massive file sizes, new developments like the HoloViewer, which is open-sourced under an MIT license, and streamlined processing tools have overcome these limitations. These tools not only allow for viewing but also for creating collision data, enabling users to navigate these 3D environments like in a video game. The applications are widespread, already being used in real estate for interior scans and now making inroads into the gaming industry, with developers building games using scanned locations. Capturing these detailed scenes has also become easier, with tools that can process scans from phone videos. This advancement allows for the rendering of up to one billion splat files, creating a highly detailed and interactive experience that is revolutionizing fields from real estate to game development and historical site preservation.
